Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If mmWave band is used to secure broad bandwidth and high data transmission rate, then data transmission rate is improved, but path loss increases and signal penetration ability deteriorates

Engineering Contradiction:
Improvedata transmission rateVSAvoidsignal transmission stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent segments the signal reception function by using multiple antenna modules (first antenna module and second antenna module) to receive control information and data from different transmission nodes. This segmentation allows the system to form multiple reception beams simultaneously, compensating for path loss through spatial diversity and improving signal reliability in mmWave bands

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a spatial dimension by forming beams in different directions using multiple antenna modules. The first reception beam and second reception beam are formed in different spatial directions to receive signals from different transmission nodes, transforming the problem from a single-dimensional signal path to a multi-dimensional spatial reception system, thereby mitigating path loss effects

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Length of stationary object

If beamforming technology is used to transmit signals to electronic devices, then transmission distance is improved, but device complexity increases

Engineering Contradiction:
Improvetransmission distanceVSAvoidantenna module configuration
Core Design Contradiction:
Length of stationary objectVSDevice complexity

Solution Approach 1:

The patent makes the antenna modules universal by enabling each antenna module to perform multiple functions: receiving control information from transmission nodes, receiving data from different transmission nodes, and forming reception beams in different directions. This multi-functionality reduces the need for specialized hardware for each function, thereby managing device complexity while achieving extended transmission distance

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements dynamic beamforming where the processor dynamically selects and configures antenna modules based on reception quality measurements. The system can adaptively switch between different antenna modules and beam configurations to maintain optimal transmission distance, making the complex beamforming system manageable through dynamic adaptation rather than static configuration

Inventive Principle:
Principle #15Dynamics

3Reliability

If multiple antenna modules are used to receive data from multiple transmission nodes, then signal reception reliability is improved, but device complexity increases

Engineering Contradiction:
Improvesignal reception stabilityVSAvoidantenna module and processor configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent performs preliminary actions by having the processor pre-configure multiple antenna modules and pre-form multiple reception beams before data transmission. The system预先 (in advance) establishes the reception infrastructure, so when data arrives from multiple transmission nodes, the system can immediately process signals without complex real-time configuration decisions, thereby improving reliability while managing complexity through advance preparation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements self-service through automatic reception quality measurement and automatic antenna module selection. The processor automatically measures reception quality of control information from different transmission nodes and autonomously selects the appropriate antenna module and reception beam configuration without external intervention. This self-service capability improves reception reliability while keeping the control logic manageable

Inventive Principle:
Principle #25Self-service
